Take humane control of your pup’s environment to prevent pants munching. This means using a combination of baby gates, safe (supervised) tethering and teaching your pup to settle in a crate so you can use these tools for brief “time outs” when necessary.

Teach your puppy that it is fun to behave differently (Sit to greet or touching his nose to your hand, for example). Be sure to pick new behaviors which are incompatible with biting pants

Create a consistent, two pronged sequence when your pup is in a pants biting mood.

The sounds or words you use for the warning cue and the time out cue do not matter so long as a) they do not scare your puppy and b) you use the same word or sound every time and so does everyone else who handles your pup. Consistent patterns and cues make learning easy.

You may need to repeat the bite-warn-time out-repeat process several times before your puppy perceives the very predictable pattern that the way to win (keep you around) is to either not bite your pants or to bite the toy instead of your pants when given the chance. But, in my experience, if your efforts are consistent and clear, they do catch on eventually!

Last but not least, make sure your puppy is getting enough exercise and sufficient opportunity for “puppy crazy time.” You may find that the pants biting activity peaks at dawn and dusk. Some puppies need to be left alone in a dog safe area for a while at peak activity times early in the morning and again in the late afternoon or early evening so they can “go nuts” by themselves, tossing toys, chewing bones and playing until they fall asleep in an adorable heap.
